Question 20
XE-GNAT2 marksNeeds review
An orange juice sample is concentrated from 10% to 40% (by weight) total soluble solids in a single effect evaporator with a feed rate of 3600 kg hr−1 at 25°C. The evaporator operates at sufficient vacuum to allow the product moisture to evaporate at 55°C. The specific heat of both feed and concentrated juice is 4.0 kJ kg−1 °C−1. If enthalpy of water vapour at 55°C is 2600 kJ kg−1, heat transfer rate through the heating surface area of the evaporator in kilowatt (in integer) will be _____.
